We often say that “food is the God of the people”, and food is the type of culture that the people are most proud of. All kinds of food with various colors and flavors are appetizing, but if it is difficult to swallow while eating delicious food, it is definitely not a particularly good experience. Many people with such abnormal symptoms, will be nervous to check the Internet, hope that everything is their own illusion, the results were countless or professional or amateur people told “esophageal cancer”, in fact, if only from the point of view of the symptoms, chronic pharyngitis and its similarity to the two clinically misdiagnosed each other from time to time, not to mention the patient’s self-guessing. Early Symptoms of Esophageal Cancer Early symptoms of esophageal cancer: In the early stage of esophageal cancer, patients have almost no uncomfortable symptoms, or the symptoms are not obvious. With the gradual growth of the tumor in the esophagus, the patients will have a sense of swelling or tightness in the chest, which is often accompanied by dryness in the throat. Patients feel that there is always a stuffy feeling in the front part of chest, which seems to be blocked by an object and makes the chest tight, and this sense of blockage is especially obvious when swallowing food. In the early stage of esophageal cancer, patients often have a foreign body sensation when swallowing food. When swallowing food, the food (especially dry and hard food) passes through the lesion area of esophageal cancer, and the food rubs against the tumor, which will produce a foreign body sensation. This kind of foreign body sensation is always fixed in a certain area, like the feeling that something cannot be swallowed. Suddenly, weight loss inexplicably and rapidly, you should be alert to whether you have cancer. Many cancers can cause weight loss, and in the case of esophageal cancer, difficulty swallowing can exacerbate the situation. Patients with esophageal cancer may also vomit within a few hours of eating, and as the cancerous tissue spreads to the intestines, vomiting and other GI-related symptoms increase. This patient would like to have similar symptoms as long as the early symptoms of esophageal cancer, but as I said earlier, many patients would confuse chronic pharyngitis and esophageal cancer in clinic. The symptoms of the two are quite similar, both of them may present with dysphagia and a foreign body sensation in the throat, but chronic pharyngitis patients are often accompanied by coughing, and during normal eating, patients with esophageal cancer would have chest and back pain, burning sensation, while chronic pharyngitis patients’ symptoms would be relieved or disappear. The symptoms of chronic pharyngitis will be relieved or disappear instead. If you want to diagnose your own disease, it is better to determine it through examination, such as CT, esophageal endoscopy and so on. We must have a comprehensive understanding of esophageal cancer, if it can be detected as early as possible, adopt reasonable and effective treatment plan, and the patient keeps optimistic mind and actively cooperates with the treatment, it is completely possible to achieve good therapeutic effect and terminate the progression of the disease.
